SIGNORS, BY DIRECT AND MESNE ASSIGNMENTS, TO LOGAN AUTOVOLUMETER 00. OF OKLAHOMA, A CORPORATION OF OKLAHOMA REGISTER FOR GASOLINE STORAGE TANKS Application filed May 15,1929. Serial No. 363,385.

The present invention is directed to improvements in registers for gasoline storage tanks.

The primary object of the invention is to provide a device of this character so constructed that a complete tally can be kept upon the number of gallons dispensed, and further, to provide means whereby the customer can readily compute the price for a number of gallons of gasoline furnished.

Another object of the invention is to pro-- vide a device of this character having an audible signal connected therewith which will operate as each gallon of gasoline is dispensed.

. Another object of the invention is to provide a device of this character which can be conveniently connected with a'storage tank wherein a float will control the operation of the register.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a front view of-the register showing the same associated with a conventional form of gasoline pump, the pump being broken away to illustrate the relative arrangement of the float therein.

Figure 2 is a top plan view of the register.

Figure 8 is a detail view of the pawl and ratchet arrangement.

Figure 9 is a face view of one of the dial plates.

Referring to. the drawings, the numeral 1 designates a portion of the cylindrical container of a conventional pump storage'tank,

' 10 is formed on the the top 2 thereof having a pipe 3 leading therefrom in which is mounted a pulley 4. This pipe leads to the casing 5 which is suitably supported against the container 1. J ournaled transversely of the casing 5 is a shaft 6 having upon one end a loose pinion 7 and fixed ratchet teeth 8 which are located in the upper end of the supplemental casing 9 upon the rear face of the casing 5. A pinion shaft intermediate the ends thereof and'meshes with the internal teeth of the segment 10 carried by the frame 11, said frame being pivotally supported by a pin 12. The frame has an arm 13 extending therefrom and upon which is adjustably mounted a counter-weight 14. Fixed to the shaft 6 is a wheel 15, the rim 16 thereof-having a groove 17 formed therein and having one end fixed to the rim is a cable 18which passes through the pipe 3, said cable being windable and unwindable upon the rim. The cable is passed over the pulley 4 and is secured to the float 19 movable in the container 1 and governed by the rise and fall of the liquid therein. The float 19 is guided by a rod 20 in order that when liquid is being pumped into or dispensed from the container,

agitation of the float will be eliminated. Due to the presence of the segment 10' and its associated weight- 14, the cable will be held taut during the rise and fall of the float 19.

A ring 21 is arranged concentric with the shaft 6 and carries a plurality of spaced pins 22, certain of which are secured to the spokes 23 of the wheel 15, the purpose of which will later appear.

A pin '24 is fixed to one wall of the casing 5 and serves as a pivotal support for the arm 25 and detent 26. The arm has a'striking head 27 adapted to engage the spring gong 28 supported bythe post 29. The detent will obviously lift the arm 25 when the pins 22 are traveling in one direction so that the head 27 will be lifted and then released to strike the gong. The pins22 are spaced so that as each gallon of gasoline is dispensedthe gong will besounded. When the wheel is rotated in a reverse direction the detent may ride over the pins 22 without sounding the gong. Upon referring to Fig.

5, it will be noted that the detent and the arm 25 have a rule hinge connection so that the detent, engaged by the pins 22 when the latter are moving in one dlrection, will yield to the pins and its pivotal end will move from the adjacent end of the arm, whereas, when the pins aremovinfi in the opposite direction, the detent wi be swung so that its pivoted end will abut the end of the arm and m consequently, the arm will be raised. A lea spring 30 is so placed below the arm 25 as to support the arm normally out of contact with the gong. When the arm 25. drops, the spring will yield momentaril and permit the head 27 to strike and will t en act to elevate the arm slightly in order that thegong will sound clear y.

The wall 31 of the casing has a sight opening 32 formed therein. Removably fixed to go the wheel 15 by brackets 33 is a dial plate 34 upon one face of which are appropriately applied numerals which indicate the number of gallons and the price of one allon or a number of gallons. When the oat 19- descends, the shaft 6 will be rotated through the medium of the cable and wheel so as to rotate the dial plate 34 to position the figures correspondlng to the number of gallons dispensed in registration with the sight 80 opening 32.

Rotatable on the extended end 35 of the shaft 6 is adisc 36 in whichis formed a plurality of spirally disposed slots 37, each having marked adjacent thereto, fi res denot- 35 ing the prevailing price of gaso 'ne per gallon. The disc is held against the adjacent wall of the casing 5 and 1s rotated manually by the knob 38, there being a spring 39 to positively prevent accidental rotation of the 7 disc during rotation of the shaft 6. As shown in Figure 1, the slot bearing the price 25 is in re 'stration with the sight opening 32 while displayed through said openin is the number 5 coinciding with an in icating wire 40, which denotes that five gallons of asoline have been dispensed and at twentyve cents per gallon the cost is clearly shown to be one dollar and twenty-five cents. This disc is obviously rotated only when the price of fiasoline changes.

stub shaft 41 .is mounted in the supplemental casing 9 and has rotatably mounted thereon a dial 41' having peripheral teeth 42 which mesh with the pinion 7 of the shaft 6 so that when said shaft is rotated the dial 41' will be likewise rotated. This dial has a spiral groove 43 formed therein and has 'marked'thereon numerals designating gallons of gasoline, and each'time gasoline is dispensed the dial 41' will be rotated a dis tance to correspond to the number of gallons dispensed. This dial is so marked that it need not be reset for a long period but at indicate the number of gallons dispensed.

-, the end of each business day the dial will In order to accomplish this, a frame 44 is provided and slidable on a guide rod 45, said frame having a ointer 46 adapted to coincide with a num or u on the d1al 41. The frame is further provlded with an extension 47 which engages the groove 43 so that upon rotation of the disc 41 the frame will slide upon the rod 45. It will, of course, be understood that the extension is initially placed at the innermost point in the groove 43 so that it will travel upwardly upon the rod as the disc 41 is rotated.

The dial 41 has fixed centrally thereof a gear 48 which meshes with the teeth 49 of abarrel 50 which is supported sultably within the supplemental casing and is provided with a keyhole 51 so that upon the insertion of a key the disc may be rotated to a reset position. a The pinion 7 carries a pawl 52 for engagement with the ratchet teeth 8 in order that the dial 41' can be reset without rotating the shaft 6. A push pin 53 is slidable in the cas-- ing 5 and is adapted, when pushed inwardly, to engage the rim 16 to hold the same to positively prevent rotation thereof as the pawl 52 drags over the ratchet teeth 8.

It will be apparent that when the container 1 is being refilled, the segment 10 will act to prevent the cable becoming slack, the weight )f the float being such that it will operate the segment as the liquid in the container 1 is dispensed.

From the foregoing, it is thought that the I construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be-understood that various changes in the size, shape, and proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

The float 19' has carried thereby toggle links 17 which are pivotally connected to the posts 18' and have their overlapped meeting ends connected with the cable 18. To the outer ends of the links are pivotally connected the bars 19' slidable through the float. These bars will obviously engage the bottom of the container whenthe last gallon is dispensed, thus swinging the links 17 to take up on the cable and accelerat the wheel 15 in order that the gong will sound upon disupon rotation of the shaft in one direction,

a wheel connected with the shaft, connections between the wheel and float for rotating the shaft upon the rise and fall of the float, a graduated dial rotatably supported by the casing and having peripheral teeth meshing with the pinion, said dial having a spiral groove therein, a guide fixed adjacent and parallel with the dial, aframe slidably mount ed on the guide and having an extension at one end slidably engaging the groove in the dial to impart movement to the frame u on rotation of the dial, and a pointer carried by the frame for cooperation with the graduations of the dial.

2. The combination of a container, a float therein, a registerin mechanism mounted on the container, a ca 1e extending from the float and connecting with the registering mechanism to operate the same, to gles connecting the float and the cable, an elements depending from the toggles through the float to impinge upon the bottom of the container and cause the toggles to take u the cable.

In testimony whereof we a our signatures.
